ジャーナル フリーThe two green-bodied Argiope chloreis Thorell 1877 and A. chloreides Chrysanthus 1961 from Southeast Asia were shown to be distinct species on the basis of morphological and multi-gene data analyses. The two species recorded interspecific uncorrected p-distances of 7.87−8.83% and 8.21−9.18% based on COI and COII datasets, respectively. Individuals of A. chloreis from Peninsular Malaysia and East Malaysia are considered to be conspecific based on the relatively low intraspecific p-distance as well as similarities in their epigynal structure. Phylogenetic analysis of the COI+COII+H3A dataset has demonstrated that A. chloreis and A. chloreides are sister to each other, and related to A. aemula (Walckenaer 1841) and A. anasuja Thorell 1877. The morphological and genetic characteristics of male A. chloreides were described for the first time.抄録全体を表示PDF形式でダウンロード (18957K) -

ジャーナル フリーA new species of the genus Wendilgarda is described as Wendilgarda ruficeps sp. nov. from Japan. Both sexes of this species possess a bicolor body: prosoma reddish orange and opithosoma dark grey, which is useful for distinction from other congeners. The male palpal morphology of this species is similar to that of W. sinensis and W. muji, but can clearly be distinguished by the serrated edge on the posterior side of the median apophysis. The female epigyne of this species is similar to that of W. sinensis; however, it shows the smaller invagination on the posterior margin of the epigyne and the wider scape.抄録全体を表示PDF形式でダウンロード (15664K) -

ジャーナル フリーDuring a survey of the gnaphosid spider fauna of Iran, two interesting species of Drassodes Westring 1851 were collected. Drassodes marusiki sp. n. (♂♀, Isfahan Province, central Iran) is described as new to science, and its relationship with the closely related D. bifidus Kovblyuk & Seyyar 2009 (Turkey) is discussed, and Drassodes robatus Roewer 1961, which was originally described from Afghanistan, is recorded for the fauna of Iran for the first time; a redescription for its male and the first description for its female are provided.抄録全体を表示PDF形式でダウンロード (10300K) -

ジャーナル フリーParasitism by the ichneumonid ectoparasitoid, Brachyzapus nikkoensis, on the agelenid spider, Allagelena opulenta is recorded for the second time with the first voucher specimen. The attacked host was an adult in contrast to the exclusive utilization of juveniles of the main host, Agelena silvatica. All published records of parasitism upon Agelena silvatica are from spring to early summer, and therefore this finding of parasitism in the end of September, would be consistent with B. nikkoensis shifting its hosts in accordance with their body size, seasonal prevalence and their availability, as previously suggested.抄録全体を表示PDF形式でダウンロード (2598K)
